Rectorseal M12154 Dual Run Capacitor 55+5 Mfd 370V Oval

Product Description

The RECTORSEAL M12154 is a dual run capacitor rated at 55 plus 5 microfarads (MFD) and 370 volts, designed to support both the compressor and fan motor circuits in a single oval-body component. Dual run capacitors store and release electrical energy to help start and maintain motor operation in air conditioning and heat pump systems. The oval form factor fits standard capacitor brackets commonly found in residential condensing units. Licensed HVAC technicians install and replace this component during seasonal maintenance, motor swap-outs, or when a failed capacitor is diagnosed as the cause of a non-starting compressor or fan motor.

This capacitor is suited for residential and light-commercial HVAC applications where a single oval-style dual run capacitor serves both the compressor and the condenser fan motor. Its 370-volt rating covers the operating range of standard single-phase residential air conditioning condensing units. The compact oval housing measures approximately 1.806 inches wide by 2.806 inches long by 5.25 inches tall, making it a practical fit in tight electrical compartments inside condensing unit cabinets.

Key Features

• Dual run capacitor design supports both compressor and fan motor from a single unit
• 55 plus 5 MFD capacitance rating for standard residential AC compressor and fan circuits
• 370-volt rating compatible with typical single-phase residential condensing unit voltage requirements
• Oval body profile fits common OEM capacitor mounting brackets without modification
• Compact dimensions allow installation in space-restricted electrical compartments

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light-commercial single-phase air conditioning and heat pump condensing units requiring a 55 plus 5 MFD, 370-volt oval capacitor.

Installation Notes

A licensed HVAC technician should perform capacitor replacement. Disconnect and lock out power to the condensing unit at the disconnect box before opening the electrical compartment. Capacitors retain a high-voltage charge even after power is removed and must be safely discharged before handling. Follow NEC guidelines and local electrical codes when servicing capacitor circuits.
